Is my purchased license activated?
The purchase is activated automatically after finishing the payment. There is no product code for the license - product codes only come with the licenses for Android. You don't need a product code - the purchase is bound to your Apple ID (account). Your Apple ID is the account you use to access Apple services like the App Store, Apple Music, iCloud, iMessage, FaceTime, and more.
You can verify that a subscription or product is activated by going to the Sygic application menu → Sygic Store → Restore/Manage your purchases. At the top, you will see Your licenses section - if your subscription or product is listed here, that means it is activated on your device (no need to restore it in this case).
